Application filed December 5, 3.918. Serial. No.

To all whom it may concern:

Be it known that I, ADAM E. FENDRICLT; a citizen of the United States,residing at Weehawken, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in Toothbrushes; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in tooth brushesand more particularly to the rotary type and has for its primary objectthe provision of a guard that will prevent the lips of a person frombeing drawn in between the guard and the brush during the operation ofthe device, thereby obviating any danger of injuring the lips.

Another object of this invention is the provision of means which willpermit the removal of the brush from the guardat any time desired.

A further object of this invention is the provision of a tooth brush ofthe above stated character, which shall be simple dura ble andellicient, and which may be manufactured and sold at a comparatively lowcost.

lVith. these and other objects in view as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination, and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description, and accompanying drawing, in which Figure 1is a side elevation of a tooth brush constructed in accordance with myinvention,

Figure 2 is a vertical sectional view of the same with the coverremoved,

Figure 3 is an end elevation illustrating the guard with its open endand the guard flanges,

Figure 4: is a detail sectional view of the cover.

Referring in detail to the drawing the numeral 1 indicates a handle ofhollow formation to rotatably support an operating rod 2 that extends orprojects beyond each annular shoulders 5 and 6 are formed upon the otherend of the rod 2 said end or the rod is provided with a screw threadedsocket 7 to receive the screw threaded end of a shank 8 of a brush 9.The shank 8 has secured thereto in spiral formation bristles 10 so as toform a brush of a rotary type.

A semi-circular guard 11 is formed on the end of the handle 1 and partlyencloses the brush 9. The end of the handle 1 tapers towards the guard11 as illustrated at l9- and said guard at its point of formation to thehandle is provided with a groove 13 to reccive the shoulder 6 to preventendwise movement or the operating rod in the handle during the use ofthe device. The groove 13 is provided. with a comparatively low wall 14cproviding a construction wherein a slight bending or flexing of the endof the operating rod 2 will permit the shoulder 6 to be disengaged fromthe groove 13 when desiring to remove the operating rod from the handle1 and after the removal of the operatingmember 4:. The free end of theguard ll. is open to permit the removal of the brush 9 from theoperating rod 2 or to permit of the removal of the operating; rod 2 fromthe handle 1. liaterally extending flanges 15 are formed upon theC(lgfGS o ii'the guard 11 to prevent a persons lips "from being drawn inbetween the guard and the brush during the rotation oi the brush.

it cover 16 ot substantially semi- 'ircular shape in cross section isprovided along its edges with retaining flanges 1'? that are oil suchshape to form grooveslttl that receive the flanges 15 when the cover isslid onto the guard in an endwise direction. One end of the covercarries a circular end wall 18 that is adapted to close the open end ofthe guard 11 when said cover is applied, thereby completely housing; thebrush within the guard. The other end of the cover 16 is inclined asillustrated at 19 to conform to the inclined end 12 of the handle 1. i

From the foregoing description taken in ii e actuating member t is de-60 connection with the accompanying drawing, it will be noted that whenit is desired to use the device for cleaning teeth, the cover 16 is slidendwise from the guard 11 exposing the brush 9 whence the same is placedagainst the teeth and held in one hand with the handle 1 and with theother hand the operating rod 2 is rotated or oscillated by the actuatingor operating member 4. When the device is in use, the lips of the personbear against the guard flanges 15 and prevent them from being drawn inbetween the guard and the brush.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination, and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.

Having thus described my invention, what 1 claim is 2- A tooth brushcomprising a hollow handle, an operating rod journaled in said handleand extending beyond the end thereof, a brush carried by one end of therod, a guard carried by the handle to receive a portion of the brush, anannular collar adjacent said end of the rod, said guard having a grooveto receive the collar and having one wall of a less height than theother to permit the collar to ride over the same when the rod ismanually flexed.

In testimony whereof I allix my signature in presence of two witnesses.
